Let me count the ways. The user interface is well thought out and intuitive. While it IS "different" to have to momentarily push in a knob to select the digit that sets the current or voltage you want, you'll get used to it quickly. The coarse knobs default to the whole unit of amps or volts and the fine knobs select the digits to the right of the decimal. The digits borrow and carry as you spin the rotary encoder knobs so that, if you wanted, you could go from 0 to 10 Amps in 1 milli-amp increments. After you quit changing settings, the display reverts to actual measured voltage/current/watts. The unit was well behaved on power up and shutdown and there were no transients observed. A HUGE plus for me was that it survived multiple shorts applied while at the full 30 volts output. I went from no load to shorting the leads together several times and the supply took it. That would have been instant death for a similarly priced Chinese supply I had purchased previously, I kept a stock of a particular transistor on hand for those occasions when I fried it. There is apparently a capacitor directly on the output since shorting the supply when it's set to 30 volts results in a pretty loud snap and sparks. This means that the current limiting only works on a sustained basis. Conceivably, if you're working on something with delicate traces, you might want to use some external resistor on the supply to provide some instantaneous current limiting. This behavior is tolerable now that I know about it, supplies that are flawless cost considerably more.

The supplied leads are decent and fairly substantial so I'm not sure why some people complained . Those who knocked off stars because their supply had a max output of 23 volts need to read other reviews then change the 220V/110V switch on the back, then go back and change their review and apologize to the folks who made this wonderful device.

This supply is significantly better than a similar supply that is currently Amazon's best seller in the category. (Kungber) The FINE knobs have no weird end of rotation. The power switch is right in front where it should be. No internal trace blew up when dumping the output capacitor.

This supply so far, is bullet proof. A quiet fan kicks on if you work the supply hard. The only thing defective about the unit that I got is that the audible short circuit alarm doesn't work but I don't care about that enough to bother Amazon about it. It was a bargain at $69 though if I had waited a day, I could have got it for $55, oh well.

So far I've used this to test classic telegraph sounders. Various small products, and a couple ham radios.
Setting the right voltage and current limits are easy.
The small footprint makes it workbench friendly.
A very useful tool at a very reasonable price

Light weight but powerful. Has constant voltage and constant current selection. Great for charging batteries. has USB out put for quick charging. It replaced a power supply that was 4x the size and weight. Great buy.

The DC supply is perfect, it is small and can be used on the desk for college work when you don't want to stay in the labs. I really liked it, if you need a dual supply, you can make a differential arrangement with resistors and capacitors.

This 0-30V/0-10A CC-CV power supply is small, easy to use, and accurate. I've charged up 3 batteries so far and it has worked perfectly; my multimeter always showed the same voltage and current the device was reporting. It looks really nice too, and has great display. The controls feel good and work well. And the price was great. Not much more to say, the thing just works exactly like it's supposed to. Definitely recommend.
